Description
Unregisters a set of classes.
Call UnRegisterClasses to unregister several persistent object classes in a single line. When a class is unregistered, it can't be loaded or saved by the component streaming system.
The AClasses parameter specifies the classes (descendants of TPersistent) to unregister.
Note: In C++, the AClasses_Size parameter indicates the index of the last class in the AClasses array (one less than the number of classes).
After unregistering a class, its name can be reused to register another object class.
